Now we will focus on the method of reducing the plate-making shrinkage rate of ready-to-wear laundry products:
1, in order to get customer orders, it is necessary to see clearly whether the garment is washed or washed fabrics, can also be seen from the customer's sample clothes, garments washed clothes, the surface of the surface of the car clear lines have a significant shrinkage phenomenon Just like the side seams of the jeans that we usually wear, there are fabric lines with varying shades; if the fabrics are washed, this will not be the case. The shrinkage rate of the fabric washing does not need to be controlled. After the large goods fabrics are obtained, they go to the washing factory and then do the washing as required, and the shrinkage of the lathes can be controlled.
2, there are several ways to wash clothes divided into a variety of ways, especially jeans, there are ordinary washing, washing, washing and so on. From the customer to get a large fabric sample, at least five meters more than the entire fabric. Separately cut the entire width of the 1.2-meter-long three-piece fabric, and make a one-meter-size square on the fabric respectively. Make a mark on the fabric with a car line.
3, according to customer requirements to tell the washing plant washing requirements, after washing the test fabric to confirm the effectiveness of the customer (some customers will also ask to be a sleeve-like or trouser legs-like), a leave their own.
4. The fabrics tested by the washing factory must be dried thoroughly, touched on the hand, and must not have humidity. Measure the dimensions of the car on the fabric. The previous test with three pieces of fabric was used to test the accuracy of the shrinkage rate. Example: The length of the vertical dimension (straight wire 绺) is now 97%, which means that the longitudinal shrinkage of the fabric is 3%; the horizontal dimension (crossbow 绺) is 92%, indicating that the transverse shrinkage of the fabric is 8%.
5. According to the horizontal longitudinal shrinkage rate measured above, the size of the length of the garment length should be 78 cm when the pattern is produced. When doing the printing, 78CM X (1+3%) = 80.34 CM; the requirement of the bust The size is 56 centimeters, so when making the edition, do 56CM X (1+8%) = 60.48 CM.
6. After the correct bulk fabric arrives at the factory, it must be re-tested to prevent mistakes. In each batch of fabrics, each roll of fabric is cut into 1.2 meters of the entire width of the door and re-washed. If there are several batches of shrinkage that differ by more than 3-5CM, two or more samples must be made. Version.
Here again to remind, fabrics made of clothes washed must be repeated many times to test fabric shrinkage, do not be afraid of trouble. Sometimes even the same clothing, because the shrinkage of the fabric is different, you may want to do a lot of different types of shrinkage.
Common fabric shrinkage reference value:
Cotton, about 4.5-5%
T/C cloth, about 2%
Jinmian class, about 3%
Corduroy, about 5%
Taslan, about 3-5%
If the difference with the above values ​​is large, then the fabric production process may not meet international standards.
